FIELD OF THE INVENTION

This invention relates to a new catalyst or catalyst precursor. More particularly this invention relates to a novel mixed transition metal oxide and its use as a catalyst or catalyst precursor such as a hydrocarbon conversion catalyst or catalyst precursor or specifically a hydroprocessing catalyst or catalyst precursor. The hydroprocessing may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking.

BACKGROUND

Currently there are two main drivers for refiners to invest in hydroprocessing technology. The first being environmental regulations imposing more stringent specifications on fuels including gasoline, diesel, and even fuel oils. For example, permitted sulfur and nitrogen levels in fuels are significantly lower than one decade ago. A second driving force is the quality of crude oils. More refineries are facing crude oils containing higher concentrations of sulfur and nitrogen compounds which are difficult to process or remove by conventional processes. Without new technology, refiners resort to increasing the severity of hydrotreating processes either by increasing the reactor temperatures or decreasing space velocity through the reactor. Increasing reactor temperature has the drawback of shortening catalyst lifetime. Decreasing space velocity, through increasing reactor size or decreasing feed flow rates, has the drawback of overhauling the reactors or significantly reducing production rates. Therefore, a highly active hydroprocessing catalyst is needed. A highly active hydroprocessing catalyst helps the refiners meet the stringent fuel sulfur and nitrogen limitations without significant investment in reactors and equipment and while maintaining production rates.

In the early 2000s, unsupported, also called “bulk”, hydrotreating catalysts were applied in commercial hydrotreating processes. These catalysts were claimed to have several times more activity than conventional supported NiMo or CoMo hydrotreating catalysts based on the same loading volumes. However, to achieve the high activity, the unsupported hydrotreating catalysts often contained significantly more metal content than the conventional supported hydrotreating catalysts. Increased metal content means the cost of the catalyst is also increased. Thus, there is a need in the industry for an unsupported catalyst with better intrinsic activity per mass. An unsupported catalyst with higher intrinsic activity per mass will require less metal loading to achieve the same activity as the unsupported catalyst with less intrinsic activity at the same loading volumes.

U.S. Pat. No. 6,156,695 described a Ni—Mo—W mixed metal oxide material. The XRD pattern of this material was shown to be largely amorphous with only two crystalline peaks, the first at d=2.53 Angstroms and the second at d=1.70 Angstroms. U.S. Pat. No. 6,534,437 described a process for preparing a catalyst comprising bulk catalyst particles having at least one Group VIII non-noble metal and at least two Group VIB metals. The metal components were stated to be at least partly in the solid state during the material synthesis reaction with solubility of less than 0.05 mol/100 ml water at 18° C. U.S. Pat. No. 7,544,632 showed a bulk multi-metallic catalyst composition containing quaternary ammonium, [CH₃(CH₂)_(d)N(CH₃)₃], where d is an integer from about 10 to about 40. U.S. Pat. No. 7,686,943 described a bulk metal catalyst comprising metal oxidic particles containing niobium as a Group V metal, a single Group VIB metal, and a single Group VIII metal. U.S. Pat. No. 7,776,205 described a bulk metal catalyst comprising a single Group VIB metal, a Group VB metal, and a Group VIII metal.

U.S. Pat. No. 8,173,570 showed co-precipitation to form at least a metal compound in solution selected from Group VIII, at least two Group VIB metal compounds in solution, and at least one organic oxygen containing chelating ligand in solution. The organic oxygen containing ligand has an LD50 rate larger than 700 mg/kg. U.S. Pat. No. 7,803,735 showed forming an unsupported catalyst precursor by co-precipitating at least one of a Group VIB metal compound, at least a metal compound selected from Group VIII, Group IIB, Group IIA, Group IVA, and combinations thereof, and at least one of an organic oxygen-containing ligand.

CN 101306374 described a catalyst of at least one Group VIII metal, at least two Group VIB metals and an organic additive. The organic additive is selected from organic ammonium compounds with the formula of C_(n)H_(2n+1)N(Me)₃X or (C_(n)H_(2n+1))₄NX where n=2-20 and X denotes Cl, Br, or OH. The XRD provided shows peaks at d=11.30+/−1.5 Angstroms, d=4.15+/−0.5 Angstroms, d=2.60+/−0.5 Angstroms, and d=1.53+/−0.5 Angstroms.

Unsupported NiZnMoW materials have been discussed in Applied Catalysis A: General 474 (2014) page 60-77. The material was synthesized in two steps. The first step prepared layered NiZn hydroxides. The second step prepared the NiZnMoW material via the reaction of layered NiZn hydroxide and solution containing MoO₄ ²⁻ and WO₄ ²⁻.

There is a need for new materials to meet increasing demands of conversion processes including the need for catalysts with higher intrinsic activity per mass. The material disclosed herein is unique and novel in elemental composition as compared to previous materials.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a novel mixed transition metal oxide material, a process for preparing the material, and a process using the material. The material has an empirical formula: (M_(I) ^(a))_(m)(M_(II) ^(b))_(n)(M_(III) ^(c))_(o)O^(e) _(q) where: M_(I) is a metal or a mixture of metals selected from Group VIII (IUPAC Groups 8, 9, and 10); M_(II) is a metal selected from Group VIB (IUPAC Group 6); M_(III) is a metal selected from Group VIB (IUPAC Group 6) which is different from M_(II); a, b, c, and e are the valence state of M_(I), M_(II), M_(III), and O; m, n, o, and q are the mole ratio of M_(I), M_(II), M_(III), and O, wherein m/(n+o) is from 1/10 to 10/1, wherein n/o>0 and 0≤o/n≤100, wherein q is greater than 0; and wherein a, b, c, e, m, n, o, and q satisfy the equation: a*m+b*n+c*o+e*q=0 the material further characterized by an x-ray diffraction pattern comprising the peaks in Table A:

TABLE A 2θ (°) d (Å) 100(I/I₀)  8-14  6.320-11.043 vw 34.5-36.5 2.460-2.598 vs 53-55 1.668-1.726 s-vs 55-58 1.589-1.668 w-m 58.5-62.5 1.485-1.576 vw 62.8-63.8 1.458-1.478 m wherein the peak at 2θ (°) of 55-58 has a full width at half maximum larger than 3°.

Patterns presented herein in tabular form were obtained using standard x-ray powder diffraction techniques. The radiation source was a high-intensity, x-ray tube operated at 45 kV and 35 mA. The diffraction pattern from the copper K-alpha radiation was obtained by appropriate computer based techniques. Powder samples were pressed flat into a plate and continuously scanned from 3° and 70° (2θ). Interplanar spacings (d) in Angstrom units were obtained from the position of the diffraction peaks expressed as θ, where θ is the Bragg angle as observed from digitized data. As will be understood by those skilled in the art the determination of the parameter 2θ is subject to both human and mechanical error, which in combination can impose an uncertainty of about ±0.4° on each reported value of 2θ. This uncertainty is also translated to the reported values of the d-spacings, which are calculated from the 2θ values. The intensity of each peak was determined by the peak height after subtracting background. To prevent errors in peak deconvolution, the background is taken to be linear in the range delimiting the broad diffraction features, 6-2 Å. I_(o) is the intensity of the peak at 2θ of 34.5-36.5°. I/I_(o) is the ratio of the intensity of a peak to I_(o). In terms of 100(I/I_(o)), the above designations are defined as:

vw=0-5, w=5-20, m=20-60, s=60-80, and vs=80-100. It is known to those skilled in the art, the noise/signal ratio in XRD depends on scan conditions. Sufficient scan time is required to minimize noise/signal ratio to measure peak intensities.

Although M_(I) is a metal or a mixture of metals selected from Group VIII (IUPAC Groups 8, 9, and 10), in one embodiment M_(I) may be selected from Fe, Co, Ni, and any mixture thereof. Although M_(II) is a metal selected from Group VIB (IUPAC Group 6) in one embodiment, M_(II) is selected from Cr, Mo, and W. Although M_(III) is a metal selected from Group VIB (IUPAC Group 6) which is different from M_(II), in one embodiment M_(III) is selected from Cr, Mo, and W so long as M_(III) is different from M_(II).

TABLE A 2θ (°) d (Å) 100(I/I₀)  8-14  6.320-11.043 vw 34.5-36.5 2.460-2.598 vs 53-55 1.668-1.726 s-vs 55-58 1.589-1.668 w-m 58.5-62.5 1.485-1.576 vw 62.8-63.8 1.458-1.478 m wherein the peak at 2θ (°) of 55-58 has a full width at half maximum larger than 3°. Additional peaks may comprise 2θ (°) 18-21, d (Å) of 4.227-4.924, with 100(I/I_(o)) of vw to w; 2θ (°) 21-23, d (Å) of 3.864-4.227, with 100(I/I_(o)) of m to s; 2θ (°) 30-32, d (Å) of 2.795-2.976, with 100(I/I_(o)) of m to s. In one embodiment, the XRD pattern of the material comprises a peak between 2θ of 21° and 23°; a peak between 2θ of 34.5° and 36.5°; a peak between 2θ of 53° and 55° a peak between 2θ of 55° and 58° with the full width at half maximum (FWHM) larger than 3°; and a peak between 2θ of 62.8° and 63.8°.

The material of this invention can be prepared by co-precipitation by forming a reaction mixture in a protic solvent comprising the sources of transition metals, basic solution, and at least one short-chain alkyl quaternary ammonium halide compound. Suitable protic solvents include water and alcohols such as ethanol, isopropanol, butanol, and glycol. Suitable basic solutions are discussed above. The reaction mixture may be formed by adding the components of the reaction mixture in any order and in any combination and as a variety of solutions. In one embodiment, the sources of M_(I), M_(II), and M_(III), may be in one or more solutions prior to forming the reaction mixture. In one embodiment, sources or solutions of M_(I), M_(II), and M_(III) may be mixed with protic solvent, basic solutions, a short-chain alkyl quaternary ammonium halide solution, or any of the above prior to combination to form the reaction mixture. In another embodiment, the prepared M_(I), M_(II), and M_(III) solutions can be added into protic solution and basic solution and a short-chain alkyl quaternary ammonium halide solution added to the protic solution to form the reaction mixture. In yet another embodiment, solutions of sources of M_(I), M_(II), and M_(III) in protic solvent can be added simultaneously together with the basic solution and a short-chain alkyl quaternary ammonium halide solution to form the reaction mixture.

Depending upon the metal sources selected, the pH of the reaction mixture may be adjusted to an acidic or a basic regime. The pH of the mixture may be adjusted through the addition of a base such as NH₄OH, quaternary ammonium hydroxides, amines, and the like, or conversely through the addition of a mineral acid such as nitric acid, hydrochloric acid, sulfuric acid, hydrofluoric acid, or an organic acid such as citric acid or malic acid, depending upon reactive sources of metals. In one embodiment, the pH does not need to be adjusted.

During or after mixing the components including, the protic solvent, the basic solution, the short-chain alkyl quaternary ammonium halide solution, and sources of M_(I), M_(II), and M_(III), the reaction mixture is reacted at temperature in the range of about 25° C. to about 200° C., or from about 60° C. to about 180° C., or from about 80° C. to about 150° C. in a sealed autoclave reactor or in a reactor open to ambient pressure. The sealed autoclave reactor or the reactor open to ambient pressure can be equipped with a stirring device to mix the reaction mixture. In another embodiment, the sealed autoclave or the reactor open to the ambient pressure does not have a stirring device and the reaction is conducted at a static state unless the temperature of the reaction mixture is higher than boiling point of the mixture, causing autonomous stirring by the boiling of the reaction mixture. In embodiment where a reactor open to ambient pressure is employed, a reflux device can be optionally attached to the reactor to avoid solvent loss when the reaction temperature is close to or above the boiling temperature of the reaction mixture.

The reaction time may range from about 0.5 to about 200 h, or 0.5 h to about 100 h, or from about 1 h to about 50 h, or from about 2h to about 24h. Optionally, the reaction mixture may be mixed continuously or intermittently during the reaction. In one embodiment, the reaction mixture is mixed every few hours. During reaction, the pH of the reaction mixture can vary autonomously due to the thermal decomposition of basic compounds at elevated reaction temperatures, or the pH of the reaction mixture may be adjusted manually by adding acidic or basic compounds into the reaction mixture, depending on the desired pH. The pH of the mixture may be adjusted through the addition of a base such as NH4OH, quaternary ammonium hydroxides, amines, and the like, or conversely though the addition of an acid such as a mineral acid such as nitric acid, hydrochloric acid, sulfuric acid, hydrofluoric acid, or an organic acid such as citric acid or malic acid. In one embodiment, the pH does not need to be adjusted. As the reaction progresses, a slurry is formed. At the end of the reaction time, the pH of the slurry may be from about 6 to about 9, or from about 6 to about 8.5, or from about 6 to about 7.5. The slurry may need to be adjusted by adding acidic or basic compounds into the slurry to obtain the desired final pH. The mixed transition metal oxide material is recovered from the slurry.

In a specific embodiment, the mixed transition metal oxide material may be present in a composition along with a binder, where the binder may be, for example, silicas, aluminas, silica-aluminas, titanias, zirconias, natural clays, synthetic clays, and mixtures thereof. The selection of binder includes but is not limited to, anionic and cationic clays such as hydrotalcites, pyroaurite-sjogrenite-hydrotalcites, montmorillonite and related clays, kaolin, sepiolites, silicas, aluminas such as (pseudo) boehomite, gibbsite, flash calcined gibbsite, eta-alumina, zicronica, titania, alumina coated titania, silica-alumina, silica coated alumina, alumina coated silicas and mixtures thereof, or other materials generally known as particle binders in order to maintain particle integrity. These binders may be applied with or without peptization. The binder may be added to the bulk mixed transition metal oxide material, or may be incorporated during synthesis. The amount of binder may range from about 1 to about 80 wt % of the finished composition, or from about 1 to about 30 wt % of the finished composition, or from about 5 to about 26 wt % of the finished composition. The binder may be chemically bound to the mixed transition metal oxide material, or may be present in a physical mixture with the novel mixed transition metal oxide material. The mixed transition metal oxide material maybe extruded or pelletized with or without a binder.

At least a portion of the mixed transition metal oxide material, with or without a binder, or before or after inclusion of a binder, can be sulfided in situ in an application or pre-sulfided to form metal sulfides which in turn are used in an application. The sulfidation may be conducted under a variety of sulfidation conditions such as through contact of the mixed transition metal oxide material with a sulfur containing stream or feedstream as well as the use of a gaseous mixture of H₂S /H₂. The sulfidation of the mixed transition metal oxide material is performed at elevated temperatures, typically ranging from 50 to 600° C., or from 150 to 500° C., or from 250 to 450° C. The sulfiding step can take place at a location remote from other synthesis steps, remote from the location of the application where the mixed transition metal oxide material will be used, or remote from both the location of synthesis and remote from location of use. The materials resulting from the sulfiding step are referred to as metal sulfides which can be used as catalysts in conversion processes.

As discussed, at least a portion of the mixed transition metal oxide material of this invention can be sulfided and the resulting metal sulfides used as catalysts in conversion processes such as hydrocarbon conversion processes. Hydroprocessing is one class of hydrocarbon conversion processes in which the mixed transition metal oxide material is useful as a catalyst. Examples of specific hydroprocessing processes are well known in the art and include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking. In one embodiment, a conversion process comprises contacting the mixed transition metal oxide material with a sulfiding agent to generate metal sulfides which are contacted with a feed stream at conversion conditions to generate at least one product.

The operating conditions of the hydroprocessing processes listed above typically include reaction pressures from about 2.5 MPa to about 17.2 MPa, or in the range of about 5.5 to about 17.2 MPa, with reaction temperatures in the range of about 245° C. to about 440° C., or in the range of about 285° C. to about 425° C. Contact time for the feed and the active catalyst, referred to as liquid hourly space velocities (LHSV), should be in the range of about 0.1 h⁻¹ to about 10 h⁻¹, or about 2.0 h⁻¹ to about 8.0 h⁻¹. Specific subsets of these ranges may be employed depending upon the feedstock being used. For example, when hydrotreating a typical diesel feedstock, operating conditions may include from about 3.5 MPa to about 8.6 MPa, from about 315° C. to about 410° C., from about 0.25/h to about 5/h, and from about 84 Nm³ H₂/m³ to about 850 Nm³ H₂/m³ feed. Other feedstocks may include gasoline, naphtha, kerosene, gas oils, distillates, and reformate.

Examples are provided below to describe the invention more completely. These examples are only by way of illustration and should not be interpreted as a limitation of the broad scope of the invention, which is set forth in the claims.

Patterns presented herein (may be in tabular form) were obtained using standard x-ray powder diffraction techniques. The radiation source was a high-intensity, x-ray tube operated at 45 kV and 35 mA. The diffraction pattern from the copper K-alpha radiation was obtained by appropriate computer based techniques. Powder samples were pressed flat into a plate and continuously scanned from 3° and 70° (2θ). Interplanar spacings (d) in Angstrom units were obtained from the position of the diffraction peaks expressed as θ, where θ is the Bragg angle as observed from digitized data. Intensities were determined from the integrated area of diffraction peaks after subtracting background, “I_(o)” being the intensity of the strongest line or peak, and “I” being the intensity of each of the other peaks. As will be understood by those skilled in the art the determination of the parameter 2θ is subject to both human and mechanical error, which in combination can impose an uncertainty of about ±0.4° on each reported value of 2θ. This uncertainty is also translated to the reported values of the d-spacings, which are calculated from the 2θ values. The intensity of each peak was determined by the peak height after subtracting background. To prevent errors in peak deconvolution, the background is taken to be linear in the range delimiting the broad diffraction features, 6-2 Å. I_(o) is the intensity of the peak at 2θ of 34.5-36.5°. I/I_(o) is the ratio of the intensity of a peak to I_(o). In terms of 100(I/I_(o)), the above designations are defined as: vw=0-5, w=5-20, m=20-60, s=60-80, and vs=80-100. It is known to those skilled in the art, the noise/signal ratio in XRD depends on scan conditions. Sufficient scan time is required to minimize noise/signal ratio to measure peak intensities.

In certain instances, the purity of a synthesized product may be assessed with reference to its x-ray powder diffraction pattern. Thus, for example, if a sample is stated to be pure, it is intended only that the x-ray pattern of the sample is free of lines attributable to crystalline impurities, not that there are no amorphous materials present. As will be understood to those skilled in the art, it is possible for different poorly crystalline materials to yield a Bragg reflection at the same position. If a material is composed of multiple poorly crystalline materials, then the peak positions observed individually for each poorly crystalline materials would be observed in the resulting summed diffraction pattern. Likewise it is possible to have some Bragg reflections appear at the same positions within different, single phase, crystalline materials, which may be simply a reflection of a similar distance within the materials and not that the materials possess the same structure.
